Treatment Technology Selection
Matching the right treatment technology to the actual odor — three or four common technologies cover most plant situations.
Chemical Scrubbers (Wet Scrubbers)
Multi-stage chemical scrubbers using caustic and oxidant solutions are the workhorse for high H2S loading.
Biofilters and Biotrickling Filters
Biological treatment of odorous air — low chemical cost, butsensitive to moisture and loading.
Activated Carbon Adsorption
Activated carbon adsorbs odorous compounds — high removal efficiency, but the carbon eventually becomes saturated.
Hybrid Systems
Most real plant odor control uses multiple technologies in series — each catching different compounds or providing redundancy.
